Abstract

Describes the Government’s Standard Assessment Procedure (SAP) for assessing the energy performance of dwellings. The SAP rating is based on the energy costs associated with space heating, water heating, ventilation and lighting, less cost savings from energy generation technologies. The SAP rating is expressed on a scale of 1 to 100, the higher the number the lower the running costs. Applicable to self-contained dwellings.
